Abstract (en)

[origin: EP2298834A1] Provided are a rubber composition which is remarkably reduced in generation of rubber burning and excellent in degradation durability and which has a high elastic modulus and a rubber composition which exerts a high heat resistant adhesive property and a wet heat adhesive property and which is excellent in an adhesive property with metal such as a steel cord. The above rubber composition is characterized by comprising a rubber component, a sulfenamide base vulcanization accelerator represented by the following Formula (I), a compound having a disubstituted or trisubstituted benzene ring in which at least one of the substituents is a hydroxyl group and a methylene group donor: (wherein R 1 is a branched alkyl group having 3 to 12 carbon atoms; R 2 is a linear alkyl group having 1 to 10 carbon atoms or a branched alkyl group having 3 to 10 carbon atoms; R 3 to R 6 are a hydrogen atom, a linear alkyl group or alkoxy group having 1 to 4 carbon atoms or a branched alkyl group or alkoxy group having 3 to 4 carbon atoms, and they may be the same or different; x represents an integer of 1 or 2, and n represents an integer of 0 or 1).
